  • Type-4 PHR Another solution is to define a new type of PHR for the scenario that only a PUCCH transmission is transmitted. It is assumed that PUCCH is transmitted on a primary component carrier (PCC) and PUSCH is transmitted on a secondary component carrier (SCC) . While there is PHR type for PUSCH transmission only, no PHR type for PUCCH transmission is defined in NR. Therefore, the new type of PHR, Type-4 PHR should be introduced. Based on the formula introduced in paragraph [0062] , the PH calculation for Type-4 PHR is as following:
  • the main concern is how to enabling the Type-4 PHR for the simultaneous PUCCH/PUSCH transmissions.
  • One solution is to reuse the enabling configuration for the simultaneous PUCCH/PUSCH transmissions. Based on the agreement in RAN1#104-e, the simultaneous PUCCH/PUSCH transmissions over different cells can be RRC configured within the same PUCCH group or dynamic indication is in discussion. If this enabling RRC or dynamic indication is configured, a default configuration can be defined. In other word, this indication has an additional meaning. If there is only PUCCH transmission transmitted in the corresponding serving cell, the Type-4 PHR is configured. This solution can save more signalling overhead and accommodate the new situation.
